The following table describes the Spanning Tree Port Configuration Menu options.

Table 114 Spanning Tree Port Configuration Menu options

Command

Description

 

 

prior <0-255>

Configures the port priority. The port priority helps determine which bridge

 

port becomes the designated port.

 

In a network topology that has multiple bridge ports connected to a single

 

segment, the port with the lowest port priority becomes the designated port

 

for the segment.

 

The range is 0 to 255, and the default is 128.

 

RSTP/MSTP: The range is 0 to 240, in steps of 16 (0, 16, 32...) and the

 

default is 128.

 

 

cost <1-65535>

Configures the port path cost. The port path cost is used to help determine the

 

designated port for a segment. Generally speaking, the faster the port, the

 

lower the path cost.

 

The range is 1 to 65535. The default is 100 for 10Mb ports, 10 for 100 Mb

 

ports, 4 for Gigabit ports, and 2 for 10Gb ports.

 

A value of 0 indicates that the default cost will be computed for an auto-

 

negotiated link speed.

 

RSTP/MSTP: The range is 1 – 200000000, and the default it 20000 for

 

Gigabit ports, 2000 for 10Gb ports.

 

 

link autop2pshared

Defines the type of link connected to the port, as follows:

 

auto—Configures the port to detect the link type, and automatically

 

match its settings.

 

p2p—Configures the port for Point-To-Point protocol.

 

shared—Configures the port to connect to a shared medium (usually a

 

hub).

 

This command only applies when RSTP is turned on. See the “Common

 

Internal Spanning Tree configuration” section for more information.

 

 

edge disableenable

Enables or disables this port as an edge port. An edge port is not connected

 

to a bridge, and can begin forwarding traffic as soon as the link is up.

 

Configure server ports as edge ports (enabled).

 

This command only applies when RSTP is turned on. See the “Common

 

Internal Spanning Tree configuration” section for more information.

 

 

fastfwd disableenable

Enables or disables Port Fast Forward on the port.

 

 

on

Enables STP on the port.

 

 

off

Disables STP on the port.

 

 

cur

Displays the current STP port parameters.
